MVXLAN（Multicast VXLAN，组播VXLAN）是一种在VXLAN或EVPN VXLAN网络中进行组播业务传输的技术，实现了点到多点的高效数据传递。
S6800系列交换机中，产品代码为LS-6800-32Q、LS-6800-2C或LS-6800-4C的机型不支持组播VXLAN功能。
在组播VXLAN组网中，需要注意：
· 组播接收者侧VTEP必须配置为Border模式，建议将组播源侧VTEP也配置为Border模式。
· 以太网服务实例的报文匹配规则不能配置为encapsulation s-vid vlan-id-list、encapsulation s-vid vlan-id-list c-vid vlan-id-list。
· 当同一组播VXLAN隧道存在对个出接口时，出接口的类型必须一致。类型包括：VLAN虚接口、三层以太网接口和三层以太网子接口等。
当同一组播组内的组播源和组播接收者通过同一AC接入VTEP时，组播报文会在该AC上出现源端口进源端口出的现象，用户需要根据实际情况，在端口下配置端口隔离组（通过port-isolate enable命令配置）和水平分割功能（通过forwarding split-horizon命令配置）来解决此问题。需要注意，对于MAC转发模式的组播数据通过配置端口隔离组来解决此问题；对于IP转发模式的组播数据通过配置端口隔离组和水平分割来解决此问题。解决此问题后，经过该聚合端口进入设备的组播报文将不再从源端口转发出去。
目前，MVXLAN仅支持IPv4 Underlay网络，不支持IPv6 Underlay网络。
单播隧道不支持在同一个组播组中作为两个INTVSI的出口。
目前，组播VXLAN支持两种工作模式：
· 入方向复制模式：实现在VXLAN网络中传输不同VPN实例的组播流量。
· MDT（Multicast Distribution Tree，组播分发树）模式：实现在EVPN VXLAN网络中传输组播流量。
组播VXLAN既支持IPv4站点网络（即私网组播网络为IPv4网络），又支持IPv6站点网络（即私网组播网络为IPv6网络）。本文以IPv4站点网络为例，介绍MVXLAN的工作机制。IPv6站点网络的MVXLAN工作机制与此类似。
入方向复制模式组播VXLAN的典型组网如图1-1所示。Border设备与VTEP设备之间手工建立VXLAN隧道，并与VXLAN关联。组播源连接到Border，组播接收者连接到VTEP。Border接收到组播源发送的组播流量后，能够区分流量所属的VPN，并在对应的VPN内通过VXLAN隧道将组播流量转发到远端VTEP。VTEP再将组播流量转发给组播接收者。
入方向复制模式组播VXLAN组网中，Border和VTEP上需要进行如下组播相关配置：
· 在Border上创建VSI虚接口，将该接口与VPN实例绑定，并在该接口上开启IGMP功能。
· 将Border连接组播源的接口与VPN实例绑定。
· Border和VTEP上，均需要在VSI视图下开启IGMP snooping功能。
入方向复制模式组播VXLAN的组播表项学习过程为：
(1) 在Border的VSI虚接口上开启IGMP功能后，该接口将在其关联的VXLAN内广播发送IGMP查询报文。
(2) VTEP从VXLAN隧道上接收到IGMP查询报文后，将VXLAN隧道接口设置为IGMP snooping的路由器端口。VTEP解封装报文，并将其发送给本地主机。
(3) 如果本地存在组播接收者，则接收者回复IGMP成员关系报告报文。
(4) VTEP将接收到IGMP成员关系报告报文的AC设置为IGMP snooping的成员端口，并通过路由器端口（VXLAN隧道接口）将该报文封装后发送给Border。
(5) Border从VXLAN隧道上接收到IGMP成员关系报告报文后，将该VXLAN隧道接口设置为IGMP snooping的成员端口。
完成组播表项学习后，组播流量将按照表项进行转发：
(1) Border接收到组播流量后，判断流量接收接口所属的VPN实例，在该VPN实例内查表转发组播流量。
(2) 如果组播流量的出接口为VSI虚接口，则在该VSI虚接口对应VXLAN内查找IGMP snooping成员端口（VXLAN隧道接口），通过这些VXLAN隧道接口将组播流量转发给连接组播接收者的远端VTEP。
(3) VTEP从VXLAN隧道上接收到组播流量后，解封装该报文，并将其通过IGMP snooping成员端口转发给相应的组播接收者。
MDT模式即在公网上建立以组播源所在的VTEP为根，组播接收者所在的VTEP为叶的组播分发树，通过单向MVXLAN隧道在公网中沿组播分发树转发组播流量，实现组播流量的最优路径转发。
MDT模式组播VXLAN具有如下优点：
· 按需转发组播流量：使用BGP EVPN路由和PIM协议搭建组播分发树、控制接收者加入或离开组播组，实现按需转发组播流量。
· 不同VXLAN之间可以转发组播流量：通过部署分布式EVPN网关，实现组播流量跨VXLAN的三层转发。
如图1-2所示，VTEP均为分布式EVPN网关，VTEP间建立MVXLAN隧道。VTEP上创建MVXLAN实例指导组播流量转发，通过本地AC和MVXLAN隧道分别将组播流量转发至本地接收者和远端VTEP。有关VTEP、VSI、VXLAN的详细介绍，请参见“VXLAN配置指导”中的“VXLAN”。有关EVPN的详细介绍，请参见“EVPN配置指导”中的“EVPN”。
· MDT：建立在属于同一MVXLAN内所有VTEP间的组播分发树，包括Default-MDT和Data-MDT两种。
· Default-Group（默认组）：每个MVXLAN在公网上分配一个独立的组播组，称为Default-Group。它是MVXLAN在公网上的唯一标志，用来在公网上建立MVXLAN所对应的Default-MDT。无论私网组播报文属于哪个组播组，VTEP都统一将其封装为普通的公网组播数据报文，并以Default-Group作为其所属的公网组播组。
· Default-MDT（Default-Multicast Distribution Tree，默认组播分发树）：以Default-Group为组地址的MDT，称为Default-MDT。MVXLAN使用Default-Group唯一标识一棵Default-MDT。在该MVXLAN中传输的所有私网组播报文，无论从哪个VTEP进入公网，都经由此Default-MDT转发。Default-MDT是在配置完成后自动生成的，在公网中将会一直存在，而不论公网或私网中有没有实际的组播业务。
· Data-Group（数据组）：当组播流量通过指定ACL规则的过滤时，入口VTEP会为其分配一个独立的组播组，称为Data-Group，并通知其它VTEP使用该组播组在公网内转发该组播数据流量。一个MVXLAN唯一确定一个Data-Group范围以便进行Data-MDT切换。在进行Data-MDT切换时，从Data-Group范围中选取一个被引用最少的地址，从VTEP进入公网、通过指定ACL规则过滤的私网组播报文将使用该地址进行封装。
· Data-MDT（Data-Multicast Distribution Tree，数据组播分发树）：以Data-Group为组地址的MDT，称为Data-MDT。下游存在接收者的VTEP加入Data-Group，形成一棵Data-MDT，入口VTEP使用Data-MDT在公网中转发封装后的私网组播数据。
为了支持MVXLAN，MP-BGP在EVPN地址族新增了如下EVPN路由用于创建MDT：
· Supplementary Broadcast Domain Selective Multicast Ethernet Tag Route：增强型广播域选择性组播以太网标签路由，也叫SBD-SMET路由，包含私网组播源地址和组播组地址信息，用于接收者侧的VTEP通告希望接收某个(*，G)或(S，G)的组播流量。该路由携带VPN实例下配置的RD和VPN实例IPv4/IPv6地址族下配置的Export target。
· Selective Provider Multicast Service Interface Route：选择性组播业务接口路由，也叫S-PMSI A-D路由，包含私网组播源地址、私网组播组地址、Default-Group或Data-Group地址及MVXLAN源接口地址。主要用于：
¡ 组播源侧VTEP与其所有BGP邻居间建立Default-MDT。
¡ Default-MDT向Data-MDT切换。
该路由携带VPN实例下配置的RD和VPN实例IPv4/IPv6地址族下配置的Export target。
在MVXLAN网络中，VTEP间会自动创建源为MVXLAN下指定的源接口地址，组地址为Default-Group或Data-Group地址的MVXLAN隧道用于转发三层组播流量。该MVXLAN隧道是由组播源端VTEP指向组播接收者所在VTEP的单向MVXLAN隧道。MVXLAN创建后会自动与MVXLAN实例关联。
公网中运行的组播路由协议可以是PIM-SM或PIM-SSM。在这两种情况下，创建Default-MDT的过程是相同的，且Default-MDT都具有以下特点：
· 网络中所有属于同一个MVXLAN的VTEP都加入该MVXLAN的Default-MDT。
· 所有属于某MVXLAN的私网组播报文进入公网后，均沿该MVXLAN的Default-MDT向各VTEP转发，无论VTEP所连接的Site中是否存在接收者。
图1-3 PIM-SM网络中创建MDT
如图1-3所示，公网中运行PIM-SM，VTEP 1、VTEP 2和VTEP 3都运行MVXLAN。以VTEP 1下的站点作为组播源为例，Default-MDT的创建过程如下：
(1) VTEP 1向VTEP 2和VTEP 3发送携带（*，*）信息的S-PMSI A-D路由给所有BGP邻居，开始创建Default-MDT。
(2) VTEP 2和VTEP 3收到S-PMSI A-D路由后，路由中携带的（*，*）信息会触发VTEP 2和VTEP 3加入组播组，即VTEP 2和VTEP 3根据路由的PMSI Tunnel属性中的组播源和组播组信息（源为VTEP 1上MVXLAN隧道源接口的IP地址，组地址为VTEP 1上配置的Default-group）发送公网PIM加入信息，并在公网沿途建立组播表项，形成以VTEP 1为根，以VTEP 2和VTEP 3为叶的SPT，此SPT就是Default-MDT。
当Default-MDT创建完成后，组播源即可通过Default-MDT将私网组播数据发送给各Site中的接收者。私网组播数据在本地VTEP上进行VXLAN封装并沿Default-MDT传输，在远端VTEP上解封装并继续在私网内传输。
如图1-4所示，网络中运行PIM-SM，属于Site 2的私网组播组G（225.1.1.1）的接收者（Receiver）与VTEP 2相连；属于Site 1的组播源（Source）向G发送组播数据；用于公网组播数据转发的Default-Group为239.1.1.1。私网组播数据跨越公网进行传输的过程如下：
(1) Source发送私网组播数据（192.1.1.1，225.1.1.1）到VTEP 1。
(2) VTEP 1上根据组播报文，在VPN实例中创建（192.1.1.1，225.1.1.1）组播转发表。如果此时Receiver已经向VTEP 2发送IGMP加入信息，VTEP 2会向VTEP 1发送携带（*，G）的SBD-SMET路由，VTEP 1根据路由中的信息对组播报文进行VXLAN封装（外层源地址为MVXLAN的源接口地址，外层组地址为Default-group地址）沿已经创建好的Default-MDT将VXLAN报文发送至所有远端VTEP；如果此时没有接收者，则丢弃组播报文。
(3) VTEP 2收到报文后，解封装VXLAN报文，还原私网组播报文，查找组播转发表将组播报文发送至本地Receiver。至此跨越公网网络的私网组播数据传输完成。
(4) VTEP 3收到报文后，解封装VXLAN报文，还原私网组播报文，发现本地没有接收者，会将组播报文丢弃。
Data-MDT和Default-MDT都是同一个MVXLAN中的转发隧道。Default-MDT由Default-Group唯一确定；Data-MDT则由Data-Group唯一确定。每个Default-Group关联一组Data-Group范围。
在公网中通过Default-MDT传送组播数据时，组播报文被传输到支持同一VPN实例的所有VTEP上，无论该VTEP所连接的Site内是否存在接收者。当私网中组播数据的传输数据比较大时，可能在公网中造成数据的泛滥。这样既浪费网络带宽，又增加了VTEP的处理负担。
为了解决上述问题，MDT模式的MVXLAN支持在连接私网组播接收者和私网组播源的VTEP之间建立专用的Data-MDT，并将组播数据流从Default-MDT切换到Data-MDT，实现按需进行组播数据转发，避免组播流量在公网中泛滥。
Default-MDT向Data-MDT切换的过程如下：
(1) 私网组播数据通过了ACL规则的过滤时，发起从Default-MDT向Data-MDT的切换。
(2) 源端VTEP从配置的Data-Group范围中选取一个引用次数最少的Data-Group地址，并将其通过S-PMSI A-D路由发送至远端VTEP，该路由中包含私网组播源地址、私网组播组地址、源端VTEP上MVXLAN源接口地址、Data-Group地址。
(3) 远端VTEP收到S-PMSI A-D路由消息后，检查本地是否有私网组播流量的接收者：如果有，则回复加入信息加入以组播源所在的VTEP为根的Data-MDT；如果没有，则将该消息缓存起来，等待有接收者时直接回复加入信息加入Data-MDT。
(4) 当组播源端的VTEP发送S-PMSI A-D路由信息一定时间后，该VTEP会停止使用Default-Group地址对私网组播数据进行封装，并改用Data-Group地址进行封装，组播数据沿Data-MDT向下分发。
(5) Default-MDT切换到Data-MDT之后，当某下游VTEP不再连接接收者时，可以通过发送PIM剪枝消息退出Data-MDT。
当私网组播数据切换到Data-MDT之后，由于情况变化导致其不满足切换条件时，组播源所在的VTEP会把此私网组播数据从Data-MDT反向切换回Default-MDT，反向切换的过程与Default-MDT切换为Data-MDT相同，此处不再赘述。只要满足如下条件之一，VTEP就会进行反向切换：
· 更改Data-Group范围后，用于私网组播数据封装的Data-Group不在新的范围之内。
· 控制私网组播数据由Default-MDT向Data-MDT切换的ACL规则发生了变化，私网组播数据不能通过新ACL规则的过滤。
如图1-5所示，组播VXLAN支持分布式聚合组网中，当VTEP 1的上行链路故障时，VTEP 2上的组播流量无法通过peer-link链路同步给VTEP 1。根据奇偶转发原则，VTEP 2只能将组播组地址为奇（或者偶）数的组播流量转发给下游接收者，导致组播组地址为偶（或者奇）数的组播流量转发异常。
通过在VTEP 1和VTEP 2上配置peer-link链路的保留VLAN功能，将peer-link接口加入到保留VLAN中，可以实现将peer-link作为逃生链路，避免三层组播流量转发失败。如图1-6所示，当VTEP 2上的（S，G）表项对应的出接口为保留VLAN接口时，peer-link接口会被添加到（S，G）表项的出端口中，VTEP 2上的组播流量会通过peer-link链路发送给VTEP 1。有关peer-link链路的保留VLAN功能的详细介绍，请参见“二层技术-以太网交换配置指导”中的“M-LAG”。
图1-6 三层组播流量通过peer-link链路进行逃生
目前，仅IPv4站点网络的MVXLAN支持本功能。
MDT模式组播VXLAN跨DC（Data Center，数据中心）三层组播互通具有如下优点：
· 按需转发组播流量：通过BGP EVPN路由感知DC外是否存在组播接收者，以此来控制ED是否将组播流量经VXLAN-DCI隧道转发至其他DC，实现按需转发组播流量。
· 不同DC使用不同L3VNI时也能互通：通过在ED上将不同DC的L3VNI映射为相同的L3VNI，或不同DC间的L3VNI相互映射，可以实现DC间相同VPN内不同L3VNI组播流量的互通。
如图1-7所示，跨数据中心三层组播互通组网中，ED之间需要建立VXLAN-DCI隧道，组播流量通过该隧道在数据中心之间转发。
ED从对端ED接收到SBD-SMET路由和S-PMSI A-D路由后，需要进行如下处理：
· SMET路由：ED根据路由的下一跳地址查找VXLAN-DCI隧道，该隧道接口作为组播流量的出接口，以便将DC内的组播流量通过该隧道转发给对端ED。
· S-PMSI A-D路由：ED将该路由的PMSI Tunnel属性中的组播源地址修改为本地ED的MVXLAN源接口地址，以便在DC内建立以该ED为组播源的Default-MDT或Data-MDT。
DC内ED和VTEP之间的BGP EVPN路由发布和MVXLAN隧道建立过程与非跨数据中心组网完全相同。
完成BGP EVPN路由发布和VXLAN/MVXLAN隧道建立后，跨数据中心三层组播流量的转发过程为：
(1) VTEP 1接收到组播源发送的组播流量后，识别流量所属的VPN，并在对应的VPN内通过组播隧道将流量转发给本DC内的VTEP 2和ED 1。
(2) VTEP 2将组播流量转发给其下的组播接收者；ED 1将组播流量经VXLAN-DCI隧道转发给DC 2内的ED 2。
(3) ED 2通过组播隧道将组播流量转发给VTEP 3，VTEP 3再将组播流量转发给组播接收者。
不同DC中的相同用户VPN使用不同L3VNI时，为了实现相同用户VPN内三层组播流量的跨数据中心互通，需要在ED进行如下处理：
· 创建一个专属的VPN实例。
· 对L3VNI进行映射，并使用映射的L3VNI与该VPN实例关联。ED上的L3VNI映射方式包括如下几种：
¡ 将不同DC的L3VNI映射为相同的L3VNI，该L3VNI称为中间L3VNI。例如，DC 1内使用L3VNI 1、DC 2内使用L3VNI 2时，在DC 1内的ED 1上将L3VNI 1映射为中间L3VNI 12，在DC 2的ED 2内将L3VNI 2映射为中间L3VNI 12。
¡ 不同DC的L3VNI互相映射。例如，DC 1内使用L3VNI 10、DC 2内使用L3VNI 20时，在DC 1内的ED 1上将L3VNI 10映射为L3VNI 20，在DC 2的ED 2内将L3VNI 20映射为L3VNI 10。
· 在VTEP和ED之间、不同DC的ED之间进行S-PMSI和SMET路由重生成，修改路由中的RD、RT和L3VNI。
图1-8 L3VNI映射示意图
如图1-8所示，DC 1的L3VNI为1，DC 2的L3VNI为2，使用中间L3VNI 12进行L3VNI映射。在该组网中，ED上路由重生成及组播转发表项建立的过程为：
(1) 在VTEP 3上配置Default-Group之后，VTEP 3会主动发送携带（*，*）的S-PMSI路由，携带的L3VNI为2。
(2) ED 2收到该S-PMSI路由（DC内）后，将其添加到用户VPN和专属VPN，在专属VPN内进行路由重生成，即替换S-PMSI中RD、RT和L3VNI（L3VNI替换为12）信息，并发送给ED 1。
(3) ED 1收到重生成的S-PMSI路由（DC外，L3VNI为12）后，将其添加到用户VPN和专属VPN，在用户VPN内进行路由重生成，即替换S-PMSI中RD、RT和L3VNI（L3VNI替换为1）信息，并发送给VTEP 1和VTEP 2。
(4) Recevier 3发送组播组G的IGMP Report报文后，VTEP 3上会生成（*，G）的组播表项，并主动发送（*，G）的SMET路由。
(5) ED 2收到该SMET路由（DC内）后，将其添加到用户VPN和专属VPN，在专属VPN内对其进行重生成，即替换SMET中的RD等信息，发送给ED 1。同时，ED 2在用户VPN内生成（*，G）组播表项。
(6) ED 1收到重生成的SMET路由（DC外）后，将其添加到户VPN和专属VPN，在用户VPN内对其进行重生成，发送给VTEP 1和VTEP 2。同时，ED 1在专属VPN内生成（*，G）组播表项，出接口为VSI接口。
(7) VTEP 1和VTEP 2收到重生成的SMET路由（DC内）后，将其添加到用户VPN，并生成（*，G）组播表项。
(8) 组播流量到达VTEP 1上后，VTEP 1会主动发送封装Default-group并携带（S，G）组播源信息的S-PMSI路由。
(9) ED 1收到携带（S，G）的S-PMSI路由（DC内），对路由进行重生成。同时，ED 1会在用户VPN内生成（S，G）的组播表项，出接口为专属VPN；专属VPN内也会生成（S，G）的组播表项，入接口为用户VPN，出接口为VSI接口，该VSI接口对应的出端口为VXLAN-DCI 隧道接口。即，流量从用户VPN进入后，通过专属VPN内的VSI接口（VXLAN-DCI隧道接口）发送出去，到达ED 2。
(10) ED 2收到携带（S，G）的S-PMSI路由（DC外），对路由进行重生成。同时，ED 2会在专属VPN内生成（S，G）的组播表项，入接口为VSI接口，出接口为用户VPN；用户VPN内也会生成（S，G）的组播表项，入接口为专属VPN，出接口为MTunnel口。即，流量从专属VPN进入后，通过用户VPN内的MTunnel组播隧道转发至VTEP 3。
目前，仅IPv4站点网络的MVXLAN支持本功能。
在跨数据中心三层组播互通组网中，为了提高ED的可靠性，避免单点故障，在数据中心的边缘可以部署多台ED设备与其他数据中心互联。这些ED设备使用相同的虚拟IP地址，虚拟成一台ED设备，并采用虚拟IP地址与VTEP、远端ED建立VXLAN隧道，以实现ED的冗余备份和负载分担。
如图1-9所示，跨数据中心三层组播互通支持多ED组网中，BGP EVPN路由发布和VXLAN/MVXLAN隧道建立过程与跨数据中心三层组播互通组网基本相同。所不同的是：
· 多ED（ED 1和ED 2）使用虚拟IP地址与远端ED（ED 3）建立VXLAN-DCI隧道。
· ED 3接收到来自DC 1的SMET路由或S-PMSI A-D路由后，将路由的下一跳修改为多ED的虚拟IP地址。
· ED不会加入同一个数据中心的其他ED的MVXLAN隧道。
完成BGP EVPN路由发布和VXLAN/MVXLAN隧道建立后，跨数据中心三层组播流量的转发过程为：
(1) VTEP 1接收到组播源发送的组播流量后，识别流量所属的VPN，并在对应的VPN内通过组播隧道将流量转发给本DC内的VTEP、ED 1和ED2。
(2) 本DC内的其他VTEP将组播流量转发给其下的组播接收者。ED 1和ED 2根据一定的原则从中选取一台设备将组播流量经VXLAN-DCI隧道转发给DC 2内的ED 3。
(3) 远端ED（ED 3）通过组播隧道将组播流量转发给VTEP 2，VTEP 2再将组播流量转发给组播接收者。

为了减少公网流量泛滥，节约带宽，可将Default-MDT切换为Data-MDT，实现组播流量按需转发。满足切换条件的组播流量不会立即切换到Data-MDT，而是等待一段延迟时间后再进行切换，以避免组播数据流量在Default-MDT与Data-MDT之间进行频繁切换。
同一台设备上，一个MVXLAN的Data-group范围不能包含任何其他MVXLAN的Default-group，也不能与其他任何MVXLAN的Data-group范围重叠。
对于同一个MVXLAN，IPv4 MVXLAN和IPv6 MVXLAN使用的Default-Group必须相同，Data-Group范围不能重叠。
所有VPN实例共用Data-Group资源，所以不建议在单个VPN实例内把Data-Group的范围配置的过大，否则会导致其他VPN实例无可用Data-Group。

执行本配置后，可以将某VPN实例的接收者的加入信息通过其它VPN实例发送至组播源，从而实现组播源和组播接收者位于不同的VPN网络之间的组播转发。
跨VPN组播转发路由的RPF选路策略分为：
· 基于L3VNI的RPF选路策略：即根据L3VNI判断是否进行跨VPN组播转发。
在组播源侧VTEP上配置该策略时，VTEP根据组播源所在VPN实例的L3VNI、组播源地址、组播组地址查找匹配的RPF选路策略。如果存在匹配的策略，则根据该RPF策略将组播流量引入到指定的VPN实例。
在组播接收者侧VTEP上配置该策略时，跨VPN组播转发机制为：
a. 组播源侧VTEP接收到组播源发送的组播报文后，为组播报文添加VXLAN头，VXLAN头中携带组播源所在VPN实例的L3VNI。
b. 组播接收者侧VTEP接收到VXLAN封装的组播报文后，如果该报文的L3VNI、组播源地址、组播组地址匹配了RPF选路策略，则根据该RPF策略将组播流量引入到指定的VPN实例。
· 基于VPN实例的RPF选路策略：即根据VPN实例判断是否进行跨VPN组播转发。
在组播源侧VTEP上配置该策略时，VTEP根据组播源所属的VPN实例、组播源地址、组播组地址查找匹配的RPF选路策略。如果存在匹配的策略，则根据该RPF策略将组播流量引入到指定的VPN实例。
在组播接收者侧VTEP上配置该策略时，跨VPN组播转发机制为：
a. 组播源侧VTEP接收到组播源发送的组播报文后，为组播报文添加VXLAN头，VXLAN头中携带组播源所在VPN实例的L3VNI。
b. 组播接收者侧VTEP接收到VXLAN封装的组播报文后，在本地查找L3VNI对应的VPN实例，如果L3VNI对应的VPN实例、组播源地址、组播组地址匹配了RPF选路策略，则根据该RPF策略将组播流量引入到指定的VPN实例。
跨VPN组网环境分为：
· 非对称跨VPN组网：组播接收者侧VTEP上不存在组播源所在的VPN实例。
该组网方式支持的跨VPN组播转发路由选路策略类型与选路策略配置的位置有关：
¡ 在组播源侧VTEP上，既可以配置基于L3VNI的选路策略，也可以配置基于VPN实例的选路策略。
¡ 在组播接收者侧VTEP上，只能配置基于L3VNI的选路策略。
· 对称跨VPN组网：组播接收者侧VTEP上存在组播源所在的VPN实例。
在这种组网中，组播源侧VTEP和组播接收者侧VTEP上，均可以配置基于L3VNI的选路策略和基于VPN实例的选路策略。
如果VTEP连接的部分组播接收者属于公网，则无论是对称跨VPN组网还是非对称跨VPN组网，都不能在RPF选路策略中指定l3-vni vxlan-id参数和vpn-instance vpn-instance-name参数。组播接收者侧VTEP上，为了实现在公网内转发组播流量的同时，将该流量引入到另一个VPN实例，需要配置与公网实例关联的L3VNI（假设为vxlan-id1），并在需要引入流量的VPN实例下配置未指定L3VNI和VPN实例的RPF选路策略（假设为policy-a）。组播接收者侧VTEP接收到L3VNI为vxlan-id1的组播报文后，如果该报文与RPF选路策略policy-a匹配，则会在公网和指定VPN实例内转发组播流量。
源VPN和接收者VPN必须运行相同的PIM模式，目前支持PIM-SM和PIM-SSM。
采用PIM-SM模式时，推荐使用下面的方式配置跨VPN选路策略：
· 只指定组播源方式：该方式下，必须配置两条选路策略，一条以服务于有跨VPN需求的组播组的RP地址作为源地址，一条以源VPN里的组播源作为源地址。如果存在多个有跨VPN需求的组播组，则推荐单独配置RP服务于这些组播组，同时需要将此RP配置为跨VPN组播路由的RPF选路策略的组播源地址。
· 只指定组播组方式：只需要配置一条指定源VPN中组播组地址的选路策略。
采用PIM-SSM方式时，推荐使用下面的方式配置跨VPN选路策略：一条同时指定源VPN内组播源地址和组播组地址的选路策略。
暂不支持通过基于L3VNI（指定l3-vni vxlan-id参数）的RPF选路策略将VSI虚接口接收到的公网组播流量（组播源所属的VSI与公网实例关联）引流到接收者VPN。
只支持一次跨VPN组播转发，接收者VPN不能同时作为源VPN，即配置VPN a引入VPN b中流量的跨VPN选路策略后，不能再配置VPN b引入VPN a中流量的跨VPN选路策略。
对于同一个组播源、组播组地址，不能同时配置基于L3VNI（指定l3-vni vxlan-id参数）和基于VPN实例的（指定vpn-instance vpn-instance-name参数）的选路策略。具体要求为：
· 采用PIM-SM模式时，对于同一个组播组地址，只能配置一条指定l3-vni vxlan-id参数或vpn-instance vpn-instance-name参数的选路策略。
· 采用PIM-SSM方式时，对于同一个组播源和组播组地址，只能配置一条指定l3-vni vxlan-id参数或vpn-instance vpn-instance-name参数的选路策略。
在一个接收者VPN（multicast routing [ vpn-instance vpn-instance-name ]命令指定的VPN）内，来自同一个源VPN的所有组播流量必须配置相同方式的选路策略，不能为不同组播源、组播组地址配置不同方式的选路策略。
如果在接收者VPN中配置了跨VPN的IPv4/IPv6组播路由的RPF选路策略，且该策略只指定了组播组地址，那么该VPN原先相同的VPN实例的组播流量转发将中断。
不同跨VPN策略的组播源地址和组播组地址范围不能完全相同，但是可以有重叠。若对于同一个（S，G）表项，存在多条匹配的选路策略，则按照最长匹配进行选择：
· 选择组地址掩码匹配最长的选路策略。
· 如果组地址掩码相同，则选择源地址掩码匹配最长的选路策略。

在两台VTEP（或Border）设备上均指定采用源接口的地址作为M-LAG系统的虚拟地址，并为VTEP（或Border）设备配置相同的源接口地址后，这两台设备将虚拟成为一台设备。该设备采用虚拟地址作为组播源地址与远端设备建立MVXLAN隧道，从而避免设备单点故障对网络造成影响。
组播VXLAN支持分布式聚合功能不能应用在如下场景：
· 暂不支持单挂AC（AC仅连接到M-LAG系统中的一台成员设备）接入。
· 仅支持以太网聚合链路作为peer-link链路，暂不支持VXLAN隧道作为peer-link链路。
· VTEP设备之间、VTEP与Border设备之间暂不支持采用M-LAG方式聚合接入。
仅支持根据组播目的地址、基于奇偶原则在成员设备之间进行组播流量的负载分担，不支持基于组播源地址进行负载分担。
当peer-link链路发生故障时，M-LAG系统中的成员设备会将MVXLAN隧道的源地址由虚拟地址转换为各自的本地地址，且不再进行Data-group切换，只沿Default-group转发流量。此时，成员设备之间不再进行组播流量的负载分担，成员设备转发所有接收到的组播流量。当peer-link链路恢复后，MVXLAN隧道的源地址由本地地址切换为虚拟地址，满足条件的情况下会进行Data-group切换。此时，成员设备之间会进行组播流量的负载分担。
如果Underlay网络的流量通过VLAN接口进入VTEP或Border设备，则建议在peer-link链路上配置不允许Underlay流量所在的VLAN通过；否则，可能会导致接收者收到两份相同的组播流量。
本配置与系统视图下的EVPN支持分布式聚合配置之间存在如下关系：
· 执行本配置的同时，需要执行evpn m-lag group命令开启EVPN的分布式聚合模式并配置虚拟VTEP/ED地址，且该地址必须与MVXLAN源接口的地址相同。
· 可以通过多种方式配置组成M-LAG系统的本地IP地址和远端IP地址。如果同时配置了多种方式，则对于某一个MVXLAN网络，优先级从高到底依次为：
a. MVXLAN地址族视图下的m-lag local命令：该配置仅对当前MVXLAN网络生效。
b. 系统视图下的multicast-vpn vxlan m-lag local命令：该配置对所有MVXLAN网络生效。
c. 系统视图下的evpn m-lag local命令：该配置对所有MVXLAN网络生效。
· 设备上需要同时使能二层组播和三层组播功能，组播VXLAN支持分布式聚合功能才能生效。
· 组播VXLAN支持分布式聚合组网中，需要在连接M-LAG系统成员设备的设备上配置BGP Add-Path（Additional Paths）功能，以便该设备从不同成员设备接收到相同前缀的BGP路由后，将这些路由都发布给BGP对等体，从而形成到达同一目的网络的多条路径。

跨数据中心三层组播互通组网中，不仅需要在VTEP和ED上完成MDT模式组播VXLAN的相关配置，还需要执行本配置，以便实现三层组播流量通过ED跨数据中心转发。
暂不支持组播源跨DC迁移。
通过BGP EVPN路由动态创建VXLAN-DCI隧道时，需要在ED间互连的三层接口上通过dci enable命令开启DCI功能。ED间手工创建VXLAN-DCI隧道时，不能在ED间互连的三层接口上开启DCI功能。
MDT模式组播VXLAN跨数据中心三层组播互通组网中，如果使用专属VPN进行L3VNI映射，则不同专属VPN实例的RT属性不能有交叉，即一个专属VPN实例的Export RT不能同时与其他专属VPN实例的Import RT匹配，以保证每个专属VPN之间路由完全隔离。
跨数据中心三层组播互通组网中，需要在ED上配置路由策略，使得ED从本DC内的其他ED、从其他DC内的ED接收到S-PMSI A-D路由和SMET路由后，不会再将该路由发送给ED设备（包括本DC内的ED和其他DC的ED）。
组播源或组播接收者直接连接在ED设备上时，暂不支持如下场景：
· 多台ED组成M-LAG系统时，组播源和组播接收者不能单挂接入到其中的一台ED设备。
· 不支持不同DC使用不同的L3VNI。
· 不支持多ED组网。
组播源或组播接收者直接连接在ED设备上时，如果dci enable或者evpn m-lag local等配置发生变化，导致流量在数据中心之间传输时的数据封装发生变化，则需要执行reset multicast vpn-instance vpn-instance-name forwarding-table all命令重置私网组播转发表项。
使用VXLAN-DCI隧道时，如果通过l3-vni命令配置的L3VNI值大于16000000，那么跨数据中心的组播流量将无法正常转发。

缺省情况下，组播DCI功能处于关闭状态。
(5) （可选）配置修改BGP EVPN路由中的信息。
a. 退回系统视图。

b. 进入BGP实例视图。

d. 配置从对等体/对等体组接收到BGP EVPN路由后，修改路由中的信息。
peer { group-name | ipv4-address [ mask-length ] } re-originated [ smet | s-pmsi ] [ replace-rt ]
缺省情况下，不修改从对等体/对等体组接收到的EVPN路由的信息。
不同DC内相同VPN使用不同的L3VNI时，需要执行本命令。
本命令的详细介绍，请参见“EVPN命令参考”中的“EVPN”。
如果在设备上同时配置了s-pmsi advertise source-active命令和data-group命令，则Default-MDT向Data-MDT切换的延迟时间（由data-delay命令配置）必须大于BGP发布同一路由的时间间隔（由peer route-update-interval命令配置）。否则，通告Data-Group的S-PMSI路由可能会被BGP抑制发布，导致从Default-MDT向Data-MDT切换的过程中流量转发中断。

(2) 进入MVXLAN视图。

(3) 进入MVXLAN地址族视图。

(4) 配置通过S-PMSI路由通告激活组播源信息。
s-pmsi advertise source-active
缺省情况下，不会通过S-PMSI路由通告激活组播源信息。
配置本命令后，VTEP接收到组播流量时，会发送携带组播流量所属（S，G）的S-PMSI路由。通过该路由，VTEP和ED可以确认组播源位于DC内还是DC外。
跨数据中心三层组播互通组网中，通过配置本功能在一个数据中心中部署多台ED，可以提高ED设备的可靠性，避免单点故障。
当多台ED中的一台ED故障时，其余ED可以接管该ED的流量。ED故障恢复后，需要通告BGP EVPN路由，触发重新建立组播转发表项，该ED才可以正常转发组播报文。如果在组播转发表项建立前将流量回切到该ED，则会导致组播流量转发中断。因此，需要在所有ED上均配置回切延迟时间，确保某个ED故障恢复后，其余ED等待延迟时间再回切流量，以避免流量转发中断。
为了避免组播流量转发失败，需要在VTEP上执行vxlan default-decapsulation命令开启缺省解封装指定IPv4 VXLAN报文的功能，或在VTEP上手工创建到达同一数据中心的各个ED设备真实IP地址的VXLAN隧道。
同一个数据中心的多台ED之间需要BGP路由互通，且ED之间不能配置BGP路由重生成。
跨数据中心三层组播互通支持多ED组网中，需要在连接同一数据中心多台ED的设备上配置BGP Add-Path（Additional Paths）功能，以便该设备从不同ED接收到相同前缀的BGP路由后，将这些路由都发布给BGP对等体，从而形成到达同一目的网络的多条路径。
不能在同一DC的ED之间转发S-PMSI A-D路由和SMET路由。由于BGP的部署方式（如，同一DC内的ED之间建立全连接），使得ED之间可能会转发BGP路由时，需要在ED上配置路由策略，限制ED将从其他BGP对等体接收到的S-PMSI A-D路由和SMET路由发送给本DC的其他ED。
系统视图和MVXLAN地址族视图下均可以配置ED的回切延迟时间。系统视图的配置对所有MVXLAN网络都有效，而MVXLAN地址族视图的配置只对当前MVXLAN网络有效。对于一个MVXLAN网络来说，优先采用对应MVXLAN地址族视图的配置，只有MVXLAN地址族视图下未进行配置时，才采用系统视图的配置。
执行本配置前，需要完成跨数据中心三层组播互通相关配置，详细介绍请参见“3.11 配置跨数据中心三层组播互通”。
(1) 进入系统视图。
system-view
(2) 配置ED设备的虚拟IP地址。
evpn edge group group-ipv4
缺省情况下，未配置ED设备的虚拟IP地址。
本命令的详细介绍，请参见“EVPN命令参考”中的“EVPN”。
(3) 跨数据中心三层组播互通支持多ED组网中，在ED设备上配置属于同一个数据中心的其他ED设备的IP地址。
multicast-vpn vxlan edge remote remote-ipv4-address
缺省情况下，跨数据中心三层组播互通支持多ED组网中，未在ED设备上指定其它ED设备的IP地址。
(4) 全局配置ED的回切延迟时间。
multicast-vpn vxlan dci switch-delay delay-time
缺省情况下，ED的回切延迟时间为10秒。
(5) 进入MVXLAN视图。
multicast-vpn vxlan vpn-instance instance-name mode mdt
(6) 进入MVXLAN IPv4地址族视图。
address-family ipv4
(7) 配置ED的回切延迟时间。
dci switch-delay delay-time
缺省情况下，以系统视图下multicast-vpn vxlan dci switch-delay命令全局配置的ED回切延迟时间为准。
在完成上述配置后，在任意视图下执行display命令可以显示配置后的MDT模式组播VXLAN的运行情况，通过查看显示信息验证配置的效果。

Switch A和Switch B为分布式EVPN网关设备；Switch C为与广域网连接的边界网关设备；Switch D为RR，负责在交换机之间反射BGP路由。
Switch A、Switch B、Switch C和Switch D的公网接口均配置PIM-SM，Switch A、Switch B和Switch C使能MLD Snooping功能，用于建立组播转发表项。
虚拟机VM 1为组播源，其余VM为组播接收者，VM1和VM 3属于VXLAN 10；VM 2和VM 4属于VXLAN 20。VM 2、VM 3和VM 4均可通过分布式EVPN接收组播组FF1E::的组播流量。
图3-2 相同VPN内MVXLAN三层组播互通配置举例
(1) 配置IP地址和单播路由协议
# 在VM 1和VM 3上指定网关地址为10:1::1:1；在VM 2和VM 4上指定网关地址为10:1::2:1。（具体配置过程略）
# 配置各接口的IP地址和子网掩码；在IP核心网络内配置OSPF协议，确保交换机之间路由可达。（具体配置过程略）

Switch A和Switch B为分布式EVPN网关设备；Switch C为与广域网连接的边界网关设备；Switch D为RR，负责在交换机之间反射BGP路由。
Switch A、Switch B、Switch C和Switch D的公网接口均配置PIM-SM，Switch A、Switch B和Switch C使能IGMP Snooping功能，用于建立组播转发表项。
虚拟机VM 1为组播源，其余VM为组播接收者。VM 1、VM 2和VM 3属于VPN实例vpna，VM 4属于VPN实例vpnb。VM 1和VM 3属于VXLAN 10；VM 2和VM 4属于VXLAN 20。
图3-3 对称跨VPN组网MVXLAN三层组播互通配置举例（接收者侧配置策略）
组播接收者侧VTEP上存在组播源所在的VPN实例，该组网为对称跨VPN组网。在该组网中，组播源侧VTEP和组播接收者侧VTEP上相同VPN的RT必须相同，且只需要在与源VPN相同的VPN实例内配置组播VXLAN。
在对称跨VPN组网中，跨VPN组播转发路由的RPF选路策略既可以配置组播源侧VTEP上，也可以配置在组播接收者侧VTEP上。在组播接收者侧VTEP上，既可以配置基于L3VNI的选路策略，也可以配置基于VPN实例的选路策略。本举例仅以组播接收者侧VTEP上配置基于L3VNI的选路策略为例。
(1) 配置IP地址和单播路由协议
# 在VM 1和VM 3上指定网关地址为10.1.1.1；在VM 2和VM 4上指定网关地址为10.1.2.1。（具体配置过程略）
# 配置各接口的IP地址和子网掩码；在IP核心网络内配置OSPF协议，确保交换机之间路由可达。（具体配置过程略）

Switch A和Switch B为分布式EVPN网关设备；Switch C为与广域网连接的边界网关设备；Switch D为RR，负责在交换机之间反射BGP路由。
Switch A、Switch B、Switch C和Switch D的公网接口均配置PIM-SM，Switch A、Switch B和Switch C使能IGMP Snooping功能，用于建立组播转发表项。
虚拟机VM 1为组播源，其余VM为组播接收者。VM 1和VM 2属于VPN实例vpna，VM 3属于VPN实例vpnb，VM 4属于VPN实例vpnc。VM 1和VM 3属于VXLAN 10；VM 2和VM 4属于VXLAN 20。
图3-4 非对称跨VPN组网MVXLAN三层组播互通配置举例（接收者侧配置策略）
组播接收者侧VTEP上不存在组播源所在的VPN实例，该组网为非对称跨VPN组网。在该组网中，组播接收者侧VTEP上组播接收者所在VPN实例的RT必须和组播源侧VTEP上组播源所在VPN实例的RT相同。
在非对称跨VPN组网中，跨VPN组播转发路由的RPF选路策略既可以配置组播源侧VTEP上，也可以配置在组播接收者侧VTEP上。在组播接收者侧VTEP上，仅可以配置基于L3VNI的选路策略。本举例仅以组播接收者侧VTEP上配置基于L3VNI的选路策略为例。
(1) 配置IP地址和单播路由协议
# 在VM 1和VM 3上指定网关地址为10.1.1.1；在VM 2和VM 4上指定网关地址为10.1.2.1。（具体配置过程略）
# 配置各接口的IP地址和子网掩码；在IP核心网络内配置OSPF协议，确保交换机之间路由可达。（具体配置过程略）

Switch A、Switch B、Switch C和Switch D的公网接口均配置PIM-SM，Switch A、Switch B和Switch C使能IGMP Snooping功能，用于建立组播转发表项。
虚拟机VM 1为组播源，其余VM为组播接收者。VM 1和VM 2属于VPN实例vpna，VM 3属于公网，VM 4属于VPN实例vpnb。VM 1和VM 3属于VXLAN 10；VM 2和VM 4属于VXLAN 20。
图3-5 存在公网接收者跨VPN组网MVXLAN三层组播互通配置举例
组播接收者侧VTEP上只有公网加入，不需要配置跨VPN策略，需要配置公网实例的MVXLAN配置。
接收者侧VTEP上如果同时存在公网加入和其他私网加入，公网加入不需要配置跨VPN策略，但是私网加入必须配置不带l3-vni参数和vpn-instance参数的跨VPN策略。这种组网可以配置公网实例的MVXLAN配置或者私网实例的MVXLAN配置。
(1) 配置IP地址和单播路由协议
# 在VM 1和VM 2上指定网关地址为10.1.1.1；在VM 3和VM 4上指定网关地址为10.1.2.1。（具体配置过程略）
# 配置各接口的IP地址和子网掩码；在IP核心网络内配置OSPF协议，确保交换机之间路由可达。（具体配置过程略）

在组播VXLAN组网中，连接组播源和组播接收者的分布式EVPN网关、Border上均配置M-LAG，以提高网络的可靠性。具体需求如下：
· Switch A和Switch B连接组播源Source 1。采用M-LAG将Switch A和Switch B虚拟成一台设备，作为分布式EVPN网关。
· Switch C和Switch D连接组播接收者Receiver 1。采用M-LAG将Switch C和Switch D虚拟成一台设备，作为分布式EVPN网关。
· Switch E和Switch F连接组播接收者Receiver 2。采用M-LAG将Switch E和Switch F虚拟成一台设备，作为与广域网连接的边界网关设备Border，同时作为反射器在交换机之间反射路由。
· 所有M-LAG系统均采用以太网聚合链路作为peer-link链路。
· 在Switch A～Switch F上配置VLAN 100为peer-link链路的保留VLAN，并将peer-link接口添加到VLAN 100中，以实现上行链路故障时三层组播流量通过peer-link链路进行逃生。
· 各台设备上均使能IGMP Snooping功能，用于建立组播转发表项。
· 在各设备的公网接口上配置PIM-SM。
· 组播源Source 1、组播接收者Receiver 1、组播接收者Receiver 2均属于VXLAN 10。Receiver 1和Receiver 2可以接收Source 1发送的组播流量。

如图3-8所示，具体组网如下：
· Switch B为普通二层交换机，用于二层转发组播流量。
· Switch A为DC 1的VTEP设备，用于用户的接入。
· Switch C、Switch D为DC 1的ED设备，用于DC间的互联。Switch C和Switch D组成M-LAG系统，以提高网络的可靠性。
· Switch E、Switch F为DC 2的ED设备，用于DC间的互联。Switch E和Switch F组成M-LAG系统，以提高网络的可靠性。
· Switch G为DC 2的VTEP设备，用于用户的接入。
· DC 1和DC 2内均使用L3VNI 1000。
Switch A～Switch G连接DC内设备的公网接口上均配置PIM-SM，Switch C～Switch F上使能IGMP Snooping功能，用于建立组播转发表项。连接DC外设备的公网接口不需要使能PIM-SM。
组播源通过Switch B接入ED设备Switch C和Switch D，Switch A、Switch E、Switch F和Switch G连接组播接收者。组播接收者可接收来自组播源的组播流量。

Switch A、Switch B为DC 1的Leaf层设备，用于用户的接入。Switch C为DC 1的边缘设备，用于DC间的互联。Switch E为DC 2的Leaf层设备，用于用户的接入；Switch D为DC 2的边缘设备，用于DC间的互联。Switch G为DC 3的Leaf层设备，用于用户的接入；Switch F为DC 3的边缘设备，用于DC间的互联。
Switch A、Switch B、Switch E和Switch G的公网接口上均配置PIM-SM，Switch B、Switch E和Switch G上使能IGMP Snooping功能，用于建立组播转发表项。
Switch A连接组播源，Switch B、Switch E和Switch G连接组播接收者。组播源和组播接收者都属于vpn1，且组播接收者均可接收组播组225.0.1.1的组播流量。
DC 1内，vpn1对应的L3VNI为1001；DC 2内vpn1对应的L3VNI为1002；DC 3内vpn1对应的L3VNI为1003。在Switch C、Switch D和Switch F上使用相同的专属VPN（vpn2），对应的L3VNI为1000，使组播源发送的组播流量经专属VPN vpn2转发至其他DC，进而到达其他DC的组播接收者。
图3-9 三DC之间使用相同专属VPN进行映射配置组网图
(1) 配置IP地址、单播路由协议和PIM SM协议
# 在组播源上指定网关地址为192.168.10.1；在Receiver 1上指定网关地址为192.168.20.1；在Receiver 2上指定网关地址为192.168.40.1；在Receiver 3上指定网关地址为192.168.60.1。（具体配置过程略）
# 配置各接口的IP地址和子网掩码；在DC内配置OSPF协议，确保交换机之间路由可达。（具体配置过程略）
# 在DC内设备间相连的VLAN接口上使能PIM SM。建议不要在ED间相连的VLAN接口上使能PIM SM。（具体配置过程略）

Switch A、Switch B为DC 1的Leaf层设备，用于用户的接入。Switch C为DC 1的边缘设备，用于DC间的互联。Switch E为DC 2的Leaf层设备，用于用户的接入；Switch D为DC 2的边缘设备，用于DC间的互联。Switch G为DC 3的Leaf层设备，用于用户的接入；Switch F为DC 3的边缘设备，用于DC间的互联。
Switch A、Switch B、Switch E和Switch G的公网接口上均配置PIM-SM，Switch B、Switch E和Switch G上使能IGMP Snooping功能，用于建立组播转发表项。
Switch A连接组播源，Switch B、Switch E和Switch G连接组播接收者。组播源和组播接收者都属于vpn1，且组播接收者均可接收组播组225.0.1.1的组播流量。
DC 1内，vpn1对应的L3VNI为1001；DC 2内vpn1对应的L3VNI为1002；DC 3内vpn1对应的L3VNI为1003。为了实现不同L3VNI的互通，需要配置专属VPN：
· 在Switch C和Switch D上使用专属VPN vpn2，对应的L3VNI为1122，使组播源发送的组播流量在Switch C上经专属VPN vpn2转发至Switch D，进而到达Receiver 2。
· 在Switch C和Switch F上使用专属VPN vpn4，对应的L3VNI为1133，使组播源发送的组播流量在Switch C经专属VPN vpn4转发至Switch F，进而到达Receiver 3。
图3-10 三DC之间使用不同专属VPN进行映射配置组网图
(1) 配置IP地址、单播路由协议和pim sm协议
# 在组播源上指定网关地址为192.168.10.1；在Receiver 1上指定网关地址为192.168.20.1；在Receiver 2上指定网关地址为192.168.40.1；在Receiver 3上指定网关地址为192.168.60.1。（具体配置过程略）
# 配置各接口的IP地址和子网掩码；在DC内配置OSPF协议，确保交换机之间路由可达。（具体配置过程略）
# 在DC内设备间相连的VLAN接口上使能PIM SM。建议不要在ED间相连的VLAN接口上使能PIM SM。（具体配置过程略）

Switch A、Switch B为DC 1的VTEP设备，用于用户的接入；Switch D、Switch E、Switch F为DC 1的ED设备，用于DC间的互联；Switch C为DC 1的RR，在Switch之间反射路由。Switch J为DC 2的VTEP设备，用于用户的接入；Switch H、Switch I为DC 2的ED设备，用于DC间的互联。Switch L为DC 3的VTEP设备，用于用户的接入；Switch K为DC 2的ED设备，用于DC间的互联；Switch G设备用于连接不同DC的ED。
DC 1内使用L3VNI 1000，DC 2内使用L3VNI 2000，DC 3内均使用L3VNI 3000。不同DC的L3VNI均映射为L3VNI 4000，以实现DC间组播流量互通。
Switch A～Switch L连接DC内设备的公网接口上均配置PIM-SM，Switch A、Switch B、Switch J、Switch L上使能IGMP Snooping功能，用于建立组播转发表项。连接DC外设备的公网接口不需要使能PIM-SM。
Switch A连接组播源，Switch B、Switch J、Switch L连接组播接收者，组播接收者可接收组播组225.0.0.1的组播流量。

(1) 配置IP地址、单播路由协议和PIM SM协议
# 在Source和Receiver上均指定网关地址为10.0.0.1。（具体配置过程略）
# 配置各接口的IP地址和子网掩码；在DC内配置OSPF协议，确保DC内的路由器之间路由可达。（具体配置过程略）
# 在DC内设备间相连的VLAN接口上使能PIM SM。ED间相连的VLAN接口上不能使能PIM SM。如果ED间的接口上已使能了PIM SM功能，则需要执行pim bsr-boundary命令将ED配置为BSR的服务边界。（具体配置过程略）

Switch A为DC 1的VTEP设备，用于用户的接入。Switch B为路由反射器，用于在DC 1内反射路由。Switch C和Switch D为DC 1的ED设备，用于DC间的互联。Switch C和Switch D组成M-LAG系统，以提高网络的可靠性。Switch F为DC 2的ED设备，用于DC间的互联。Switch E为普通三层交换机，实现ED间路由可达。Switch G为DC 2的VTEP设备，用于用户的接入。DC 1和DC 2内均使用L3VNI 1000。
Switch A～Switch G连接DC内设备的公网接口上均配置PIM-SM，Switch A、SwitchC上使能IGMP Snooping功能，用于建立组播转发表项。连接DC外设备的公网接口不需要使能PIM-SM。
Switch A连接组播源，Switch G连接组播接收者。组播接收者可接收来自组播源的组播流量。

(1) 配置IP地址、单播路由协议和PIM SM协议
# 在Source上指定网关地址为100.1.1.1；在Receiver上指定网关地址为100.1.2.1。（具体配置过程略）
# 配置各接口的IP地址和子网掩码；在DC内配置OSPF协议，确保DC内的路由器之间路由可达。（具体配置过程略）
# 在DC内设备间相连的VLAN接口上使能PIM SM。ED间相连的VLAN接口上不能使能PIM SM。如果ED间的接口上已使能了PIM SM功能，则需要执行pim bsr-boundary命令将ED配置为BSR的服务边界。（具体配置过程略）
